i recently bought a bmx second hand and its basically brand new

but i'm a big guy so i'm paranoid i will destroy the crank all i ever had was one piece cranks till now and eventually i'd snap them just riding around not much into tricks and that here is a link to the bike

if i do happen to break something
what kinda stuff would i need to replace it? what size(style) is the bottom bracket shell if need to replace the bearings, or what should i get in the way of a new crank or chainwheel.

any help is appreciated

they don't specify on their site. it mentions looseball, maybe american size? post up a pic of your bikes non drive side crank arm / bb shell. that might help.

there are the pics.
and because it uses looseball does that mean i couldnt put something like this in its place ?

i doubt that exact one i just picked for example! could i put sealed bearings in a loose ball bb shell?
thanks for your help

hmm seems to be american but its still hard to tell. one of those bb's you posted 'should' work but i would make sure first. local bike shop may be more help, sorry.

You've got a loose ball bottom bracket there, and the crank spindle is threaded. Sealed bearings are not going to run well on that spindle if they fit at all. I would recommend replacing the whole crank if you break something. Check the classifieds if you're on a budget. I've had great luck with used cranks.
You do have an american bottom bracket. Make sure your purchase is made for that.
